Isn composting the only form of biodegradation?
No! There is much confusion about the term biodegradation and several organizations that support the PLA industry uses the term to state that composting is the only form of biodegradation. The ASTM defines biodegradable plastics as “a degradable plastic in which the degradation results from the action of naturally-occurring micro-organisms such as bacteria, fungi, and algae”. Biodegradation through naturally-occurring micro-organisms happen in both aerobic (compost) and anaerobic (landfill) environments.
